Fingerex-SD that is Outlook Add-In developed by Digent is the fingerprint
  security email system.
  Fingerex-SD makes Outlook application allow only the authorized fingerprint to
  access the application, and send/read encrypted emails.
  Fingerex-SD allows a user to encrypt a document with his or her fingerprint, so
  that decryption can be performed by only the same person.
  Fingerex-SD can be applied to the existing Microsoft Outlook application without
  any modification of the system.
  Fingerex-SD is an application program based on Fingerex authentication
  system.
   
 
    
Fingerex system guarantees the complete security because it independently
  operates.
When fingerprint data is transferred over the Internet, all data is encrypted.
Fingerex-SD system relies on unique fingerprint authentication structure and
  encryption to protect this fingerprint data from physical hacking.
Only the designated recipients can decrypt the encrypted document after
  fingerprint authentication.
   
    
Fingerex-SD system can operate in multiple servers; thus, if one server is
down, a back up server from other location can maintain the service.
Fingerex-SD system allows only those users, authorized by fingerprint
authentication, to access Outlook, and to read encrypted email.
SD system uses HYH file extension, so even though HYH file extension is used,
SD system analyzes a file when opening the e-mail and checks if the mail is
from SD system.
   
    
Fingerex-SD system does not have limitation on size
Fingerex-SD system is equipped with dispersion server, so if the number of
  hardware is increased, the speed of fingerprint authentication goes up.
   
    
Fingerex-SD supports Outlook or Outlook Express and is compatible with them.
Fingerex-SD minimizes the size of email by encrypting and compressing it at
the same time when sending it out.
Fingerex-SD has its own address book
   
    
  Fingerex-SD can register 10 different fingerprints.

After accessing to Fingerex-SD server by fingerprint authentication, the sender
  receives the authenticated user's encryption key in DB.
The e-mail encrypted by the user's encryption key is sent to the mail server
(SMTP).
The sequence of decrypting an e-mail by the sender's fingerprint authentication
  1. Receiving an e-mail (encryption) from the server
  2. Authenticating through Fingerex-SD server
  3. Receiving the encryption key after success of authentication
  4. Decrypting the e-mail by using the received encryption key
